Montipora Coral plate coral

[rennne39]

I have a plate coreal and the color is peeling off can some one tell what would casue this thanks alot

[Toddrtrex]

Need some more info --

Tank parameters --- with numbers
Lights/tank size.
How long the tank has been set up
How long you have had the coral.

check for nudis... do you see any bugs on a border between white and color?

[rennne39]

I don't see any bugs at all

[Salamander]

Your parameters aren't perfect. But they never are. I think the hihg pH of 9.0 is the the most likely to be a contributing factor to your problem.

Not really sure what "a" is?

You might want to look into getting some different bulbs for your MH's other than your 6,000k's.

monti's IME are bullet proof. It must be some kind of a pest.

ok the ph was 7.5 yesterday when it first start happening and today it is 9.0 and sorry the bubls are 20000k

That is a heck of a jump, and very well could be the cause of this. Did you drip too much kalk, or dose something?

[spleify]

temp 80 This seems good
ph 9.0 This seems very high What are you using to test
sp 1027 This seems a little high, but nothing major I shoot for 1.026
khppm 160.7(9dh) This seems good
ca 440 This seems good
nrite 0 Good
nrate 10 A little high, but nothing really to worry about
a .05 If this is ammonia, them this is high

What are your water cahnge routines, ie. frequecy and amout. Do you run a skimmer? Do you run any GAC(granular actived carbon)? do you run and GFO(Granular ferric oxide) or phosphate media?

[rennne39]

What are your water cahnge routines, ie. frequecy and amout.
once a week 10 %
Do you run a skimmer?
yes
Do you run any GAC(granular actived carbon)?
no
do you run and GFO(Granular ferric oxide) or phosphate media?
no

it was 7.5 so i put ph buffer in it to rise ph cause i thought it was the cause

[spleify]

What are you using to monitor your PH?

I would hold off with the PH buffer for now too.

With 10% weekly water changes I would think your params would be a little better.

What kind of sat are you using?

I don't know if this will really help or not, but I would suggest upping your water change frequency and amount for a while. See if you can get your hands on some GAC and GFO and run those in a reactor of some sort.

sera ph test



What kind of sat are you using?
instant ocean

I dont have a reactor so I will have to get but till I do is there another way to run this stuff

[aaronnohren]

I've had mine lose some color for a couple days at a time but it always bounces right back.

[spleify]

renne, IME none of the titration kits for PH are very good, its very difficult to get good results with those.

Instant ocean is a great salt.

You can get a media bag of some sort and fill it with carbon and sump it in the area of your sump that seems to have the best flow.

[ludnix]

There is an article floating around here that explains how to safely lower pH using vinegar or carbonated water, whatever you end up doing you always want to do it in small amounts over time to slowly adjust it.

[rennne39]

I went and got some prime and put that in there and also some carbon

[Iskandar]

ditch the buffer
